In Firefox and Tor Browser, I restrict the location bar completion to bookmarks, disable search, which makes a large number of bookmarks very fast to use.
Then have some Firefox "query" bookmarks selected by keywords like "g" (Google Search), "gi" (Google Image Search), "gm" (Google Maps), "d" (DDG), "w" (Wikipedia), particular shopping sites, shipping tracking number lookup, etc.
(I just realized that this is not so different from my 1996 solution, from when browsers and search engines were much more limited: https://www.neilvandyke.org/webjump/ )
