7" display options

I am starting a new project and plan to use a Teensy 4.1 connected to a 7" display. Some years ago, for a previous project, I used a RA8875 with a Teensy 3.5 via SPI and this worked well, it only used the default font and some basic font resizing. So I an wondering if the RA8875 display still the best display option or have other display drivers been written to cater for more recent, larger displays? One requirement for the new project is multiple fonts / sizes and poss. using Adafruit GFX fonts, does the RA8875 or other display liburaries have provision for different fonts?

Thanks

There has been alot of work done in the recent weeks by a few forum memeber on severl displays:
ILI9488, NT35510, RA8875/6 to support faster communication protocols such as i8080 over 8 and 16 bit wide parallel busses.
All there librarys support custom fonts, drawing APIs etc

 
Thanks Rezo, I will check out your links. Do any of the displays have SPI support? as this might be fast enough for the screen updating.
 
As for 7" displays that support SPI.
If you look up at BuyDisplay for 7" supporting SPI, they have a few

RA8876 - We do have library @wwatson has a few versions of libraries.
RA8875 - We have the RA8875 library, installed by TeensyDuino. I believe that @mjs513 has the most up to date version of this.
LT7683 - Not sure, I believe this one is compatible with RA8876, but...

There are probably others. You might look at the recent thread asking about 10" displays
