I really like Here maps. Hosted in Eindhoven, NL (apparently) and has cool stuff like panning when using spoken navigation, so "turn left" comes from the left speaker, which is something I would otherwise struggle with.

I'm using Organic Maps and I like it a lot, but nothing is as feature complete as Google Maps sadly. You always have to make a compromise.

Magic Earth is a decent alt for navigation.

I've been using Magic Earth for navigation, it's not FOSS but still has a lot of strong vouches in these sorts of communities, I believe their privacy policy has been thoroughly vetted if I recall. Works great and does what it needs to do.

For Gmail, I highly recommend Tuta, fantastic service. Paid plans are very affordable. The only thing I wish their client had was more in-depth rule customization but I may just be stupid. Admittedly setting up email forwarding from my gmail accounts has made me a bit lazy in fully switching over every single account from gmail to a tuta address, but I'm getting there.

Maps and Calendar for me
