+1 to ProtonMail. I've been using it for several years and was recently grandfathered into their Proton Unlimited plan that allows for additional domains, extra storage, etc. They have had technical issues a couple of times since I started using them, but support was always responsive and it's been overall a nice experience mail-wise.
In terms of their other products, I think they have quite a bit to go with Proton Drive (no widely available Android app is preventing me from switching from Google Drive) and Proton Calendar (unable to import large calendars, won't let you just import future events and ignore past entries to decrease space requirements).
