Tough choice!
I think it's important you go where your heart takes you otherwise you end up hankering for something that you didn't get. And that's disappointing and detracts from the pleasure.
That said.... macro isn't an issue on FF or APS-C. But as you have probably read ad nauseam, wide-angle is a different animal and housing FF lenses is more expensive, bigger and heavier.
lThere is no FF equivalent to the Tokina 10-17mm. The 8-15 is the nearest thing but if the Canon version is the same as the Nikon (which I have), it's not a zoom in practical use on an FF body: it's two lenses - a 15mm FE and a circular 8mm FE. Almost counter intuitively, the 8-15 is great on an APS-C body and does give zoom range! As you may have read though, it's doubtful that with the huge difference in price its worth buying the 8-15 for APS-C. (Alex Mustard did a review of this with Adam Hanlon a couple of years ago).
If you mainly look at your pics online and do the occasional print up to A3, I'd argue that APS-C is the way to go: price, convenience, transportability....
...... but then there is the heart issue. Will you always regret not getting an FF body? If it's any help, I went through the same dilemma when I sold my Nikon D300. I wanted FF and got the Nikon D800 with all the bells and whistles involved in housing FF WA lenses. I can't say I regretted it but my partner gave me endless stick about the amount of gear I was now transporting - and that was indeed a pain. After a few years I went back to APS-C with a Nikon D500. No regrets at all. And I use the Tokina 10-17 and the Nikon 8-15mm.
