It seems no one has mentioned Affinity Photo yet! This is an alternative to photoshop, it costs money but only 1-time price not a subscription service like Adobe. It runs on an iPad, so if you have an iPad Pencil then you can also use that for design work. I quite like it!
I used Canva a few years ago, but transitioned to using GIMP when I wanted more control. I created a template and would just have several layers that I could edit. I personally think it looks better, but that's not what to say what everyone else thinks (let alone be more clickable). I haven't checked out Canva since, so I don't know if it's any better.
FYI, GIMP is a free open source alternative to Photoshop for those that don't know.
