Choose your items

I think that's the point.

The spices are pretty good - great, portable money source that won't get you killed for being a witch. Everything else sucks.

Well ACTSHUALLY, depending on your definition of the middle ages, you wouldn’t be very likely to be killed for being a witch, since the witch hunt came into being after the Reneissance.
That said, I would also take the spices. The amount of spices in that picture would probably set me up for life. Buy a nice place somewhere in Northern Italy and live out my days learning to play the moog, amusing my medieval friends.

I choose the bottle rockets twice.

That's the most reasonable choice imo, you could probably earn a fair bit of money with those.

Motorcycle isn't abad choice. You get an alternator and a battery out if the deal. You can rig up a simple water turbine to charge it easily enough. You also get a bunch of steel, rubber/plastics, some wire, tubes, and a couple of pretty good lightbulbs (possibly even an LED one depending on the headlight/taillight). Taking the magic Moog as the 2nd option seems like the best idea considering it's magic.

Sure, but they’re terrible options because of how dumb people used to be. Like, you’d probably have to keep it secret or get called a witch or something.
Something I think would be more useful would be seeds for crops, specifically resistant to plant diseases that would have been devastating back then. Like, take some potatoes that are resistant to whatever caused the Irish famine. That wouldn’t be as likely to get you burned at the stake for being in service to the devil
- You might have some issues with potatoes in the medieval period. The Irish potato famine happened because potatoes radically changed the amount of calories you could grow on a set peice of land. The population spiked and crashed because of land efficiency dependancy over the course of years but that all happened well past the medieval period that was more the Industrial Revolution.
  The potato was not really a thing in the medieval period. They started showing up in the Renaissance as a curiosity from the new world and took a long time to actually take off since they were very unpopular as a food... Like strangely unpopular. They actually started gaining popularity first as a decorative plant.
  Mind you they are dead easy to grow so if your intention is to farm them for personal use for food security they are a solid pick. Still since they are something nobody around you would have seen before you would probably need to construct an adequate lie about how you got them.
  
  The potato famine happened because Britain stole all of Ireland's potato's. There were ships full of potatoes leaving Ireland regularly. There was no actual issue with growing food, except that potatoes were too cheap for the capitalists to profit off ofby selling them back to the Irish.
  
  Well... No. It's more complicated than that. The Irish potato famine happened because the lack of genetic diversity in the crop and a wet humid year caused a massive viral collapse ( scientific name for the blight :Phytophthora infestans) which caused the crop to turn to sludge in the ground. The effect wasn't limited to Ireland, big chunks of England, Wales and Scotland also had the crop collapse... The fact it was so deadly though and why we call it the "Irish Potato famine" and not the British / Irish /Welsh and Scottish Potato Famine ", that was mostly capitalist bullshitery. There was a lesser known " Highland Potato Famine " but Scotland got away mostly unscathed by comparison by basically holding landlords highly to account for famine relief early and received greater charitable relief due to better solidarity between Scotland and England.
  The flashpoint was all caused by the fact potatoes grow in much poorer soil than other crops the population which had seen an overall increase due to the caloric production increase. Basically the population rose because of production of the crop and then saw massive hardship because the crop when it failed could not be easily replaced by sowing other alternative crops. The viral collapse of the potato crop lasted practically a decade. If it was simply the matter of one bad year the supply and storage of other food stuffs would have softened the impact and they would have recovered over the next couple of years while they sowed other crops like they were used to doing when other crops failed... but the land literally couldn't support other crops because the soil was way too poor. It was potatoes or bust and the potatoes were damn near impossible to propagate unless you were lucky and your tiny potato patch was properly isolated... Which most people's weren't.
  Other crops like cereal grains (including some of the less popular ones like millet and corn) were bought up in bulk and imported by the British back to England but they basically diverted everything they could from Ireland early and once they had secured a sustained cereal grain supply to England from the colonies they never distributed anything back to Ireland despite the ongoing humanitarian crisis. The British were bastards who actively and "passively" contributed to the famine deaths via tremendous greed... But the potato crop failure was real and there were more than a few extra steps in the plot that was more about grain import/exports to make up for the shortfall than moving potatoes around... Because the potatoes were basically just rotted slime.

I'll exchange all that for:

Good knife and a sharpening stone
Flint for making fire
Compass
Axe
Several years of training in self defense and living off the land. (Or else they should send a Navy seal)

Edit: Ah it's a shit post, I always get those wrong 😁
