I don't know if it really matters what version of Riru + EdXposed I use. What matters is that the module is activated I guess. I still use Riru 21.3 + EdXposed 0.4.6.4 and all GB features I use work fine except for the ones I mentioned above. If Ceco advises me to upgrade to 23 + 0.5.x I'll do it just to test.
Also, 5T doesn't have capacitive keys like the 5. You can only use navigation bar keys and the vibration may be different on them.
I understand what you mean about the capacitive keys, on the other hand I'll share my setup with you. I've added the date to my Statusbar Clock mod and it does not diasappear.
