I'm using Photos managing my 50k+ RAWs library and its doable. I'm not living from photography but I consider myself serious enthusiasts. Photos has its limitations of course, but it really depends on your use case. Batch editing/processing is one of the missing features I hope apple will add in time.
There are two features Photos can be really useful for thread starter based on the initial post: "..Organizing into themes. (By Geo, by Family member in the picture, etc) Most of the time is probably spent here .." --> faces and memories
I personally love it - after initial faces processing (it took a while with 50k photos) I can select a person and create few minutes memory with smartly/automatically selected photos covering last 15 years - priceless.
Photos on its own creates memories - not all of them are relevant, but I find it fun to get last years anniversary memory when the date is coming.
