Ubiquiti has some cheap(er) switches($200) that'll do two SFP[1] ports[2]. Pretty cool that you can swap the physical transceiver, however like you said not really worth the hassle with the price of cat6/5e these days.
MikroTik has a similarly-priced weird alternative in the 953GS-5HnT-RP: SIM slots, 3 Gigabit ports, 2 SFP cages, 3x3 MIMO. No PoE out tho.
Looking at one of these for an external garage where the existing conduit from the house has the electrical supply in it already; don’t want to dig a new trench or work out how to shield cat5/6
