Europa! I personally believe exomoons and the moons in our solar system are the most viable places to host microbial life considering their positions, inventories, composition and size. If gotten a chance I'll definitely try to explore Europa and Titan!
Also gliese 482b! The exoplanet is very promising and if it gives a positive sign of atmospheric presence after the JWST launch, then we can fast forward the engineering to techs that travel in light speeds and send rovers to exoplanets!
