Distro for POS

I recently got a couple of POS pc’s (Point of sale) you know the ones that are all in one with a base to sit on a counter. The thing is they’re very old non branded devices, even the label says 2GB DDR2 while it’s actually 4GB DDR3.

Anyway, first thing I did was plug in my Ventoy and boot Debian 12 live, and guess what? Everything just works! Even the touchscreen works.

What distro do you recommend? Will be using them in a small shop with Odoo (browser based ERP)

Sorry if my writing is messed up, English is my second language.

EDIT: thank all for your input really appreciate it. I think I'm going to go with the majority of recommendations and use Debian 12 with xfce maybe. At least until I'm comfortable using immutable OS's.
