Very hard to find a good PoE++ switch that can reliably handle multiple 60-90w devices. I have two NUC (gen 7 and 11) i5 boxes with PoE hats hooked up to this; power has been rock-solid. Speed takes a slight hit vs conventional ethernet data, but small price to pay for flexibility. Heat has not been an issue running 24/7, just keep the unit and adapter in a ventilated space. The switch is also fairly quiet which is a nice surprise vs other PoE switches (including non ++) with loud fans.
I plan to add a few cameras/other small devices to the other lower power ports, and have not tried the high speed SFP, but so far very happy.
