Here's my 2 cents, might lead you into another rabbit hole.

I've dabbled in compression socks but didn't find anything tangible in my recovery process. Same results when using a massage gun and rollers to self-massage.

The new thing in our riding group has been trying are pneumatic compression boots; a couple of us bought some on Amazon to use after hard rides. IME it helps relieve the restlessness and stiffness after a hard ride or training session.
