You can essentially boil it down to: turn chat off, only join servers the parent has checked out first, and general stuff like set real-world screen time limits and enforce it. Java Edition doesn’t have much in the way of parental controls. As Java Edition has been around since the dawn of time, it makes sense that’ll have more variety when it comes to the best Minecraft servers. When it comes to picking a version, it all comes down to which has more servers you like the sound of. The only issue here is we’re working with two different versions of the same game, so Java Edition can’t connect to Bedrock Edition servers and Bedrock Edition can’t connect to Java Edition servers. Think adventure worlds, PvP, puzzle maps, that sort of thing. If you’re new to the world of servers they are, in a nutshell, gargantuan worlds created and hosted online with the intention of supporting masses of players.
