Yubikeys work great for me for 2FA or passwordless auth. NFC and USB interfaces. Very secure. Pretty durable, though USB-C is inherently less durable due to the size and complexity than the USB-A footprint. But I’ve never had an issue with mine in my pocket or purse right with my keys. But if you bend it while it’s inserted in something it can be an issue.
With a reverse proxy there’s no need for hoops unless you add some authentication mechanism on top of that. I use reverse proxies for several things so that they flow through filtering like crowdsec or fail2ban. It just routes the single port to the device on question as is. The idea is to make it indistinguishable from a fully exposed port to the user. Just have to make sure whatever system runs the reverse proxy is secured. I always make sure that nothing significant is on the system that is exposed to the internet other than the reverse proxy server and all other ports are closed internally and externally. Ideally a device that has multiple Ethernet ports works well so you can keep an ssh port open on the internally facing ethernet port for troubleshooting. Nice if they are 2.5Gbit or 10Gbit ports, too, since they route a lot of traffic. But not needed.
