@harris I don’t know if it applies where you are, but we have a local public rec center that has a buncha equipment and weights (as well as some tennis and basketball court space).

AARP is also open to folks of any age and has a bunch of free online exercise classes targeting different mobility and impact levels.

@harris Worth trying to go to a local trainer for a session or two, asking them to recommend a routine you can do at home if you're willing to buy a few weights and a cardio machine of some sort.
