At the very least I would UV disinfect anything coming from the ground and absolutely make use of a 20 micron sediment filter if only to address cognitive load: Another place, another time, coliform bacteria from the well. Super fun(not).

I vacillate between trusting my well and trusting my RO (10,5,1 micron filters, plus the membrane). But it isn't healthy to drink RO all the time and I don't wanna mess with remineralization.

My well is 100' and 13 years old.

For me I'd do a sediment filter and a charcoal filter and call it good. Send a sample out for analysis a few times a year.
