Universal housing can look like the government acquiring existing apartments from disinterested landlords that are out of compliance and then granting them on a $1 lease in perpetuity to local neighborhood coops so long as they maintain it well.
Not a complete fan, except that fines so large as the remedy is confiscation can be appropriate. No need to give away the confiscated property, though UBI would allow for tenant managed coops offering a fair bid. I'd rather see soviet style housing meant to provide a return for the builder, but affordable. UBI means there are no projects with "exclusive access" being for the troubled.
Universal food can look like mandates for grocery stores to provide non-profit collectives unfettered access to discarded items that are still perfectly edible instead of locking up dumpsters full of food that can feed people.
UBI is better. Nothing stopping grocery stores from taking advantage of non-profit collectives, compared to usual for profit alternatives. It's in their interest to provide food quality/value.
Free public transit is another great example. Do you want to have to include bus fare in the UBI? Or would it just make sense to make the buses and trains fare-free.
Free public transit offers denser transit schedules, traffic reduction, better value for work and "touristy" outings. UBI solving homelessness helps avoid turning a "cheap shelter" into a "free shelter" for "undesirables" that may make transit uncomfortable to others.
Why give people a voucher instead of just reimbursing all accredited schools directly and let folks enroll anywhere without having to manage a budget?
Before university grades, you don't need accredited schools as much as accredited testing. Internet/multimedia (30 years old revolution) has expanded education alternatives. Cash instead of vouchers. Spend as much as you want on education.

Just make them tuition free.
For University grades, it is rationed, and there is a minimum aptitude level required to gain from the experience. Would Harvard be allowed to exist alongside a public tuition free abundant system? I support subsidizing post secondary education similar to Canada (maybe outdated) where a summer job could pay for tuition and books. UBI, though, is plenty to afford university dorm + tuition lifestyle, but perhaps, if you can get into Harvard, you might prefer additional student loans if you consider the education worth the tuition price. The magic of UBI, is that you get to consider the overall value of education instead of "student program" scams on the young and foolish.
