If 120hz refresh is important to you: Tab S7 (LCD) & S7+(OLED)
If you are fine with 60hz refresh rate: Tab S7 FE or even the slightly older Tab S6 Lite are good options.
Keyboard wise, the magentic and clip-on design of the Tab S7's series makes it an awesome and secure accessory (try to wait for offers where Samsung gives a free keyboard cover).
Hope this helps!
