Spaces are not for fullscreen but for basically virtual desktops i3 linux style
Here is superior user experience:
1. Install moom. Its keyboard windows arrangement is second to none. Its two-step tiling is a killer. Ie caps-a to show a popup with all the shortcuts, then “a” letter for vertical 1/3 of the screen. Or s for middle 2/3. Or q for top left third — you can assign any letter for any portion of the screen.
2. Use option1-6 to switch between desktops
3. For example alt-4 is a desktop where you have all on one screen (suppose you have 6k xdr like i do): safari, mail, messages, telegram, hey email, reeder
alt-3 is your productivity desktop where you have things, calendar, basecamp, notes, ia writer
alt-1 and 2 is for your main work like rider ide or what have you
Alt-5 for your remote stuff like remote desktop, servers, what have you

So with this you have a mental model of where everything is always and instant switching to it. Want to see your todos and notes? Alt-3. Want to see your browser and messaging? Alt-4. You get it.
Moom is better than tiling manager for screens like 6k 32” xdr.
Otherwise tiling managers are perfectly fine. For instance on windows I use komorebi
