As someone else mentioned: yoga. Yoga classes with other people. These are solo ventures with the option of interacting with the other people there. This has similarities with other kinds of social workout classes but the difference is that can be fairly low effort, sometimes half of a yoga class lets you fall asleep!
Now you have a common interest with people that practice mindfulness, which is also something you need. A lot of the people are fit women, some might find it interesting that you are there at all and wonder if you're going down the mindfulness path.
So you can still fulfill your goal of resigning from the possibility of connection while creating the option of being social.
I like yoga but I don't feel that it's a super social activity. Maybe I just go to the wrong studios. Do you find that you talk a lot with other attendees? Or do you think the yoga itself is social?
My experience with that is that the attendees know of or attend other mindfulness, or consciousness events, sometimes colloquially called spiritual community. Its a relevant conversation starter to find out where those things are.
There is a parallel lingo and phrasing associated with them, that they gravitate towards if you speak that way.
Its a decent way to begin to see the same people in multiple places, which has a couple of benefits between you and them, as well as others around (or being introduced to others).
And finally, a yoga session is an okay date or social activity to bring someone else to.
i'd say in part that depends on how easy you are to talk to people. for an introvert it may not be social at all, and it may not be what helps if you actually seek interaction but you are to shy to initiate. on the other hand it may be just what you need. and environment where you are around others without being forced to talk to them but allowing you to slowly become comfortable over time.
