Leaving footprints of your music- best sites for sharing music?

Having just recovered from a (ridiculously mild) bout with COVID, and approaching 72, 
I'm starting to think about what I've accomplished in my life, and what I may leave behind.

Obviously, my interactions with family and faith are blessed positives, but what about the
various pieces of original music I've been involved with- as creator, or within groups.

I'd like to leave behind some footprints for future music archeologists to have a good laugh over.
But, I have no experience with sites, outside of Youtube, as uploading destinations for my videos. 

What I'm aiming for is NOT to sell music, or promo a band. Just a place to archive snapshots of some
music that I'm proud of.  Maybe where some complete stranger may serendipitously come across them,
and think "hmm not too shabby".  MAYBE even decide to perform pieces, spreading the music to new listeners.

Any sharing of good (or bad) experiences you've had would be welcome

(for giggles, here's my YouTube playlist. Originals recorded as solo, at a reunion of my college band, or
with my P&W group:   ofbpWalt Setlist on Youtube )

Thanks for listening to the ravings of an old, farty bassplayer !
