Minecraft crossplay?

So I’ve been playing Minecraft Java edition for a couple of years now and my daughter has got Minecraft on PlayStation 4, IPad and soon on the Switch. I feel like google is running me round in circles now. I’d like to create a Minecraft realm I can play alongside her and possibly invite her school friends who play on Switch. But I think from what I’ve seen that I can’t crossplay from Minecraft Java or Minecraft PS4 but can I change my laptop version from Java to Windows 10? Sorry if this seems a really obvious answer but I really don’t know if it’s possible or not.
