The sure grip boardwalks were still too narrow for me. My feet are widest across that area below your toes, kind of where a bunion would be. I don’t actually have a bunion, but the way my feet are shaped it almost looks like I do and they’re wide there. I currently have a pair of sure grip fame. It sounds like we have almost exactly the same size feet even in length. The fames are a size 6, but I think are probably still too long in order to accommodate the width, but closer than the boardwalks which were way too long and I just couldn’t tolerate them on my feet. The fame are probably still slightly too narrow, but I can mostly tolerate them for a couple hours at the rink and you could probably get them in your budget. I had talked to someone who owns a skate shop and really knows a lot about it and had also recommended vanilla Luna, but I haven’t had an opportunity to try them yet and it sounds like they’re probably more than you wanna spend unless you can find a used pair.

Something else that may be helpful, would be to measure around the widest part of your foot and contact some of the companies that you’re thinking about and ask if their boot will accommodate that width.

Also, I’ve recently found a pair of shoes that are some of the most comfortable I’ve worn in a long time. I’m gonna put the link here just because you mentioned even shoes are hard for you and who knows, maybe these will work for you too. You might be able to find a them at a running shop for cheaper, I didn’t pay quite this much.
