With QMK keyboard firmware, a single key can send shift-f10 or similar. I have a top layer key that acts as ctrl-super and also as a sticky key (I don't have to hold it) because I configured a bunch of key chords in Sway that start with those keys. Mainly focusing specific programs by appid or class. So, I'll hit that key and then b for browser, v for video (mpv), etc. You can even have keys that directly type out parentheses, no shift needed. The default layout for my keyboard had that for both parens and brackets. I found more useful things to put on those keys, though. I use a Pinky4 which takes some stuff off the outer edges compared to a 60%, but has more on the inner edges, and so I stuck that key somewhere along the upper right edge of the left half. If I were using qwerty, it'd be near t and g keys. In addition to being able to run QMK on a keyboard, you could also get a macropad, or just a second keyboard (maybe something small like a planck, could go above your main one), and have all sorts of specific binds like this. I would recommend layers instead for anything not used constantly, but a case can be made for both options. I have mouse keys in a separate layer, letting me hold a modifier with my thumb and then use something similar to an arrow key cluster to move my mouse. I even have all 4 scroll directions mapped, which lets me scroll horizontally, unlike my actual mouse. Software on the computer really affects use-case I think. In qutebrowser (or firefox + tridactyl) I just hit r to refresh a page. I never miss easy access to f5. I can also copy a page's url with yy instead of doing a dance of ctrl-l and then ctrl-c. I can still hit f5 if I have to. Like if using an unusual program or another computer with my keyboard. It sounds like due to your software choices, you use the function row a lot more than me. There are some larger split keyboards, but it's worth considering changing some of your behavior/software also.
