We recommend Canon EOS DSLRs, specifically the ones listed on our supported cameras page.
The Canon EOS cameras have a large live view with exposure simulation.
They also have smooth mechanics during capture.
Get the Canon EOS R or 5D Mark IV if you have a larger budget. If you want a full-frame camera at a lower price, look at the Canon EOS 6D.
If you have a limited budget, you can look for used Digital Rebels (or 450D/1000D) on Amazon.
