I’ve got the akai mpk mini plus - which in my opinion is perfect (with v good build quality) and packed with features like sequencers, arp, transport controls, Velocity sensitive pads, mappable knobs, mod wheels etc. etc. Will work with your modular too as has both CV and midi.
It does have mini keys so keep that in mind but personally this doesn’t bother me as I like it for portability and space. It’s also 3 octaves (37 keys) which is in the sweet spot for a smaller setup. I’ve heard good things about the Arturia, novation and native instruments keyboards too but haven’t tried them all. The Akai just works for me as I use both hardware and DAW interchangeably which it’s made for. I’d say see what features you like and what you might miss with certain keyboards and you’ll be able to form a decision that way :).
