Graphic design and larger think pad

I’m legally blind and I need to buy a new computer with a track point mouse.

I will be looking to run adobe illustrator, light burn solid works.

Possibly mine crypto too ( very secondary)

The price point is pretty steep on new vs used but there is a semi annual sale going on now and I’m looking for suggestions.

18” would be my minimum size I think because of my vision.

I’m open to any suggestions.
