Google services I still use before being unGoogled:
Voice: I have to make like 1 or 2 calls within the US a year & not worth a SIM
Maps: for when OSM isn’t cutting it & I’ll contribute the missing data after I found it
Translate: for when Yandex Translate doesn’t cut it (everything ‘free’ only works with European languages)
YouTube: no real alternative here that isn’t limited to just a piece of its scope, but viewed thru Librewolf+uBlock Origin+SponsorBlock or PipePipe
… and the last one is just basically every employer I have worked with puts all their company data on Google & it can’t really be avoided with them >:(
