Currently I search whatever I'm looking for in duckduckgo then click the maps button and it opens osm with the address filled it. Not a perfect setup lol, but it works well enough and that's something the osm team has been actively working on a lot recently.

In fact the store data, least where I live, is all there in osm and usually fairly accurate (easy to update when it's not). The geocoder (tool that converts names to cords and back) is the part that still needs some work until you can just open maps and search "starbucks" and find some crappy coffee or whatever. There used to be an app on fdroid that used the apple maps geocoder (not great but maybe better than google lol?) and it worked pretty well, but I think it got shut down or something.
