New tank, what to get?

[Skimmer Juice]

You could always run the sump on the side of the tank , thats how my tanks are set up . I like seeing my skimmer, and I grow mangroves in my sump. It sits right beside my tank on the floor , also lets me build the stand lower and have a nice top down view as well.
All in one tanks can be a good solution there are some pretty cool all in ones now . But I would find a shape I like and then try narrowing down a couple possible options
