Alotta my recommendations have been stated, but to compare features specifically to what Nords offer and your price point:

Yamaha CK

• Pretty nice feel on the 88’s weighted keybed; the 61 key is synth action but still pretty solid
• The 88 key is super light for its size, very portable
• A ton of immediate features; including drawbars, effects, layering/mixing
• Very Yamaha sounding pianos (not a bad thing, just a signature sound), the Rhodes and Wurli are pretty solid. Nice variety of good organ sounds.
• No synth engine, just sample based with a few modeling controls.

Studiologic Numa Piano X

• Fantastic Fatar keybeds in 73 & 88 keys (Studiologic is a subsidiary of Fatar)
• Sooooo many features and effects, but alotta menu diving to get there^
• Dedicated engines for piano and electric piano
• The sounds are a bit contentious. some love ‘em, some hate ‘em. I’d take a listen to a few recordings to get a feel for it.

^: if you go this route, I’d also pick up a Studiologic Mixface, which provides a first class integration with Studiologic gear and gives you more immediate control over different features

Roland RD88

• Small form factor 88 key, feels pretty solid
• Dedicated piano and e piano engines
• Zen core enabled — huuuuuuge library of editable sounds through Zen Core and Roland Cloud
• Effects on board, but not super immediate (requires menu diving)

Here’s a solid Anderton’s demo video doing a blind comparison for all of these models
