Canyon Grizl 7, Grizl CF SL 6 AXS or any similar bikes within brand or different brand in Canada

Hello Canyon Community! I've been riding a bike for years, but this year, I'm starting to get serious about riding a bicycle and I found out to be so much fun than I've think about it. So far, I'm using a City Rented Bike, BIXI (I live in Montréal) and already explored several places that's a little bit far from the city, including to the area with gravel route. I'm considering myself as a beginner in this cycling, but I want to invest in the bike that I will not feel regret to invest and will be keeping the bike for years to come. I always feel restricted by the time limit that the BIXI has and feel like I can go much further than when I'm using BIXI, especially outside of the city with no BIXI nearest bike parking station. I did some research for my new bike and it landed me to Canyon brand and 2 of this bike. I have few question before I make a purchase since I'm still new in this cycling environment and the community.

1) What's the different between Grizl 7 Grizl CF SL 6 AXL and is it justify to pay extra $750 CAD or are there any similar bikes that much more suitable for me or from different brands? (I mainly ride on the road 80% and gravel 20% and I don't really need speed since it's for the weekend and holiday recreational)

Canyon Grizl CF SL 6 AXS

2) When I tried to measure for the bike size, the website recommended me to get 2XS (I am 163.6 cm/5'3 and my inner leg lenght is 73,9 cm/2'4 and it's near the borderline with the size XS. Do I get the 2XS based on the website recommendation or up one size? (I am a short man)

I tried to do my research, but some people said that you should defineatly up size and some people even said down size (theres a 3XS in the Grizl 7, but not the Grizl CF SL 6 AXS)

3) Since Canyon doesn't have an official store in Canada, will the LBS able to accept the bike to be repair/upgrade if needed? and is it hard to shipped Canyon bike to Canada since there's no official store in here?

Thank you for your opinions, tips or recommendations!
