Part of this answer depends your specific budget/financial situation. I've been an Ableton user since 2014. I bought Live 9 Lite at the time (probably came included with a midi device I bought), because I was still in undergrad and wasn't sure if I was going to stick with it. Looking at my order history, I later bought Live 9 Standard and used that until 2018 when I upgraded to Live 10 Suite (I've since upgraded to every new version of Suite on release, including 13).

My advice, if you have the budget, get Standard and upgrade to Suite later (at a discount). Suite is _nice_ but it's really mostly bells and whistles that you don't "need" to get from Ableton. Suite has a ton of included sound packs and instruments that are certainly useful but may not be useful to you.

As for the Akai MPK Mini, that's going to be entirely subjective IMO. I've bought several midi controllers over the years, and I've settled on a few key pieces that I'm happy with. The Arturia KeyStep 37 is the perfect keyboard for my desktop. It has enough range in a compact form factor and doesn't have any features I don't need (I'm not affiliated with Arturia).

If you don't already have a midi keyboard, I would suggest grabbing an affordable one!
