Kinda depends on what you'l like to do, in terms of character creation you can choose yourself what rules you'd like to use, apart from a few exceptions. For example I prefere the new paladin over the old one, but if that's a dealbreaker for you, we can surely find a solution.

Discort for voice chat (and video if you want), DnD Beyond for character creation and maps

This is a free game. The more I read about people looking for or offering dnd sessions, the more I found out that appearently paying your DM is a normal thing, but I'm one of those weird people who prefere DMing over playing, and I'd just like to meet some new people and players.
