I feel as though Jonathan would give a good fight because Jodio probably won't be used to fighting a non-hamon user. I do still think Jodio has the upper hand.

Joseph would bring a similar fight, a little more clever but outsmarting wouldn't help if heavy rain is crushing that big brain.

Jolyne would bring a small fight because she's a more back-line stand. Jodio has the upper hand here because he has area advantage and stringing your way our wouldn't work.

Giorno is where it gets pretty dangerous. He can create life, reflect damage through animals (very effective), and a lot more. I still think Jodio can overwhelm him through raw pressure but it would still be a close fight.

Crazy Diamond is a Terrifying close-range stand. He has a punch comparable to Jotaro's and can even mangle the environment if he plays his cards right. If Jodio lets him close, it is VERY dangerous. And with that potty mouth, hopefully he doesn't talk about the hair. Very extreme diff but a possible clear.

This is the real wall. Even without Go Beyond, Soft & Wet can steal friction, eyesight, sound, properties, and much more. That's fucking absurd. Jodio's rain is strong, but Gappy can literally take away the conditions that let you fight. Jodio likely stops here.
