I haven’t used it in a while since I don’t have an active account there, but I really liked the randomizer in Deezer. It always showed me interesting songs that I hadn’t heard before.

^^ Heroic worked really well for me as well. I used it to get Affinity working. (Apart from using it for Epic Games and GOG ofc.)

I’ve tried Vivaldi mail. Might be something for you, but I just didn’t like the UI so I’m also still using the web interface for each. Looking forward to seeing others answer as well.
