Try out what you have...
...and adjust it when you see what does not work. Don't overthink this and consider everything you might do at some point in the future.
30x32 is plenty for climbing, and if it is not for you you might end up with nothing worse than walking/pushing a few steps. Find out yourself what works for you.
(If it was my bike I would probably install a 46/30 or 44/28 double and keep the standard 11-32 cassette.)
