I can see exactly one, and it's niche: the ability to safely leave tiny USB-A peripherals like flash drives, wireless dongles, and SFF YubiKeys connected while not in use (not that I'm recommending a YubiKey be left connected to a laptop when not in use).
Hubs are mostly only relevant for docking or increasing the number of ports, given that USB-A to -C adapters are so cheap (assuming they're not bundled with the peripheral in the first place) you can reasonably leave them permanently attached to larger form factor USB-A peripherals.
As for full-sized HDMI, assuming you're not talking about the hellish mini or micro HDMI as alternatives, I'll take USB-C, or even mini DisplayPort, over full HDMI, as both have decent connectors and provide more and better inexpensive options for display connectivity (though admittedly finding good active DisplayPort-to-HDMI dongles can be harder than it should be because chroma subsampling is a thing that's not frequently touched upon in product descriptions).
Same thing with the USB A ports. Not really selling point imo.
