DIY Kitchen Cabinet Makeover for Under $300 

Agreed, it is more cohesive to have the wood section look the same because that side especially faces the updated look. Then, just go for it and make the entire cabinetry consistent. While you are "in" the project phase, just keep going. You will enjoy the consistent look so much more. The upgrade looks good so keep that flow going. Good job, clever you!! And wow, the cost savings, impressive.

This is genius, great job!

Attach the sander to a hoover, there are fittings for this. You'll thank me :-)

finish the kitchen part first and maybe try more modern knobs on both cabinets. I think the wood looks cute but on video the wear is hard to see, if it starts to feel "shabby" painting will be much easier than restoring the wood. EXCEPT if you make new plywood doors to keep a wooden structure. (I guess the cabinet itself is solid wood?) New doors with reeded glass inserts could also look nice 😅 Anyways I'd finish the kitchen part first and then maybe try to make a mock up how it'd look like if all cabinets are the same. Then you can judge if it looks good or leans "clinic" bc everything's the same.

Do the same with the wood section
