Possibly worth noting that the Motorola G32 (also the reason I’m thinking about this topic in the first place) does meet all this criteria including official LineageOS support, although not DivestOS evidently.
I should also clarify that by “new” I mean currently available for purchase from the manufacturer, and not like within 1 year old or any arbitrary timeframe like that.

I guess I could just look up the price of every phone on the DivestOS 20.0 list lol
