I agree with some posters here, wait until your newborn and see if you have any more spare time. You maybe glad that you did not set up the tank after all and wait for couple years before you can do anything.

About maintenance, it depends what you gonna have in your tank. if you just have a fowlr tank then you can skip maintenance for months if nothing breaks. I won't count cleaning glass as maintenance because i do that when viewing my tank. Also i found bigger tank is easier to manage than small tank because water parameter does not swing fast or crash fast.
