Electrical junction box w/ 14 and 12 wire

I'm remodeling a kitchen. I need to junction 14 guage wires, for a lighting circuit, that are near impossible to re-route or access. Is it permissible to junction 14 guage wires in the same box with a 12 guage dining room receptacle? --Just to be clear, i wont be co-mingling 12 and 14 wires on the same circuit, they would only be junctioned in the same box.

Also, I know the rules about how many wires can be in a certain box. I was thinking about using 4S metal box with a mud-ring to ensure I have plenty of space.

Does this mean you have two separate circuits in one box? I assume one circuit is 15amp and the other 20amp. In your circuit panel are these two circuits on separate, not connected breakers?

Yes, two separate circuits.
1- general lighting circuit (15a)
1- dining room circuit (20a)

No problem having more than one circuit in junction box.
Keep the neutrals separate.
Connect all the grounds together.
