Kagi is based in the US and uses the Yandex (Russia) search-index as part of their stack. I am trying to stay away from both. But yeah, their search results are nice :)

Check out Vela Maps. It is also based on OSM but looks more like Google Maps and the search works quite well. Not sure about traffic data though.

Filen might be a good alternative to Proton Drive, especially if you pay for the whole suite but only use Drive.
