what linux OS should I install on a backup notebook if my main one is debian?

I'm your regular end user. I use my computers to edit text, audio and video, watch movies, listen to music, post and bank on the internet...

my main computer uses now debian 12.5 after abandoning xubuntu.

For my backup notebook I have several candidates:

• Simply install debian 12.5 again, the easiest choice.
• Install linux mint, so I get ubuntu but without them throwing their subscription services down my throat. I'm unsure about other advantages, as ubuntu is debian based, maybe the more frequent program updates? Kernels are also updated more often than with debian as far as I know. Do you know of other advantages?
• Go for FreeBSD: this might require a learning curve, because this is an OS I've never used. Are commands that different from debian?

other more niche linux OSs seem too much a hassle and I guess won't be as supported as the main ones.
