Thanks for the appreciation.
White colors are one of the most difficult to pop. Clean paint base and a glossy lsp choice helps create that pop. You seem to have the right product set from whats available locally (definitely lots of other options internationally).
With Meguiars ultimate wax, you dont really need to wax it weekly as its a durable wax (more like every 2-3 weeks usage). Keep in mind that the waxing process itself (applying wax with the applicator and pressure) also can induce swirls of its own incase any of the dirt is trapped beneath it. If you still like to have to just waxed look weekly, you could get yourself the meguiars spray wax and top that up after a weekly wash. More quicker to use with a microfiber towel.
You can continue using the megs white wax as the abrassives aren't strong enough (as pointed out by Bilal) to remove paint by hand (unless you start seeing your applicator turning white since your white car is a single stage solid paint). Stay a little light handed on the panel edges as those have thinner paint. Meguiars has a cleaner wax but white wax is the newer version and more suitable for your white. Using it every 3-4 months should be fine.
