Welcome back!!! Xenia and aiptasia do seem to thrive in almost any condition, but no matter which type of tank you decide to have this time, I'm sure we can help you through any questions or issues!
As far as your Maxspect Mazzara goes, there's a few ways you can support it, one of the easiest for me was the Aquatic Life suspension kit for their t5's. Worked a treat for hanging it from the ceiling. If you want to support it on the tank, there's other ways, feel free to post up in the DIY section for advice, you have no idea how many engineers we have floating around the hobby.
