Key differences in switching from LR in macOS to IOS ?

I have a 2013 Macbook Pro and an old Ipad. Both of which I want replace.

I currently use the MBP for editing (LR Classic) and hi-res printing (Canon Pixma Pro 100 S). Processing a few hundred images per year (Canon RAW). It serves as being the main house computer for docs, admin, banking, and the age as well as no further macOS system updates (security!) is the main reason for retiring it.

I could do like-for-like and get a new Macbook (not Pro) with M1 or M2 chip, plus a standard base model Ipad.

Similar price gets me a new Ipad Pro 12.9 inch 0.5 or 1tb storage. And add a mouse.

So the question really relates to the real life practicality of using an Ipad (vs MB) as primary photo editing hardware. Especially importing RAW files and the LR software experience and functions on both systems (IOS vs macOS).

I do wonder about printing on the Canon (are there even drivers for IOS), but this is not a deal breaker, since I can use the old MBP for just printing.
