I think the Yamaha 670 would be good for what your describing, if you want 88 keys. Of course there are better arrangers (but not 88 keys) and better digital pianos (but no auto-accompaniment)

Not too many options in the fully weighted 88 key arrangers, unless you get the digital piano of your choice with a module - and there are very few options with modules. Ketron, or a used Roland. But for me, that's just more stuff to set up...

Good luck, and stay safe out there!
