Help with leg fatigue: Which recovery tools and muscle creams actually work?

I’m looking into which tools are actually worth it. Right now I only have a massage ball, but what do you recommend for real improvement? Should I get a foam roller or is a massage gun better?

Also, do you use any specific creams or gels to relax your muscles before bed or right after running? Any tips to wind down and sleep better? I'd love to hear your routines!
