I have logged almost 2000 contacts and have 87 countries since June with my 7000 and a signalink into a vertical.
There is no need for spectrum display and all the other great features of the 7300 when working FT8
The CAT control takes care of band changes.
My 7000 sat for several years as well. I feel better putting it to good use.
Put it to use and have fun.
