40-50 is a good size. It has enough room for fish you can’t get for a nano but it can run on stuff built for a nano. Less expensive in my mind...

93 gallon cube with decent sump would be best IMHO. Enough water to slow down mistakes. Small enough to not kill a reasonable budget. Room enough to play with aquascape. Large enough that once u get it firgured out can springboard ya into a successful 200 gal + tank no problem!!!!
Edited to say that once u do get larger tank u will appreciate even more what a great / perfect / easy size the 93 cubes r .............
swer to this question also depends on the size of the beginner? I could not recommend a deep tank to a short person who does not scuba dive or at least like to snorkel
