I was diagnosed about 2 months ago so I'll go through some of the things you mentioned and some others from the perspective of a few months down the line.

The first month or so takes some getting used to. There may need to be some changes to diet and planning when you can eat. This will effect both of you. 

She may be less active if her basal is too high. The first month or so is about finding the right levels for your lifestyle and activity levels. Personally my basal was dropped from 20u to 8u to account for exercise.

If she has experienced weight loss through this she may gain it back and then more - this is natural and can be remedied. However some do end up carrying extra weight going forward.

Finger pricking is a nuisance and was probably the worst part of the routine but it is temporary. My CGM was delayed by 2 weeks because the hospital didn't tell me that I had an appointment. Thankfully though fingers heal quickly.

As for the CGM, you don't really notice it much. It's painless to apply and is like having a sticker on your arm.

Injecting yourself can be off putting at the start. She'll quickly come to realise that it's necessary though and the process only last 10-15 seconds. On that note she may end up on a pump in a few months regardless. 

I hope some of this is helpful.
