Welcome aboard! Your setup looks fine, tho I'd probably go
for a MF or MXF rod.
To your quoted question above, yep, its mostly preference.
I'd only recommend one if you want to learn how to cast and
fish with one. But honestly, it is not necessary to simply enjoy
the sport of fishing.
I went the baitcaster route and have only one reel with 2 rods
left (one rod is MH, the other ML - for diff techniques). I still
fish it, but not as often. And I spent $$ on the reel - a Shimano
Chronarch 50e with upgrades (had 2, sold 1 - have other brand
casters, just never use them, or passed along to my sons).
That said, I like having learned and become skilled at using one,
but after all the time I spent doing so, even with the goal of
going all baitcasting, I ended up back in the spinning gear camp
for 98% of what I do. Spinning is just (to me) simpler, less
worrisome with windy situations, equally as accurate (you have
to learn accuracy for either).
Both are tools for a job. Both work, both can "hammer", both
can "drill", etc. On a particular technique one may be better
suited than the other, but that doesn't mean you can't do said
technique with the other.
