Motherboard is very well featured for the price from strong modern high efficiency VRM to Intel NIC, good USB connectivity/BIOS Flashback and chipset cooler design among most sense making in X570 boards.
(it isn't suffocated by graphics cards)
Like said for gaming with that graphics card 3700X would do nicely for now and then could later upgrade CPU to improved architecture Zen3.
And especially if caring about noise you'll want aftermarket cooler.
Only step behind the best performing Scythe Mugen 5 would be good for any AM4 CPU and fits to basically any PC thanks to superbly balanced design.
And also price is very reasonable:

Though for just 8 cores it would be overkill.
In memory Crucial Ballistix Sport 3200MHz is one of the bang per buck choises with highly likely very good overlocking ability.
Beyond that 3200MHz 16-18-18 etc latency kits come with what ever chips happened to be at hand in that day.
Good bin (that 16-16-16 latency) 3600MHz Samsung B-dies cost arm and both legs and you'll start getting closer to 3200MHz 2x16GB kits.
Already 3200MHz 14-14-14 kits (same quality chips in absolute latency) are very expensive.
