Brooks has a pretty good online fitment guide. Which is nice in the Covid times.
If you can go to a store with a treadmill in it, they can watch you walk and run on it and make suggestions. I'd start there.
Another fan of "lock laces" here. I only used them ever in a single duathlon two years ago, but as a cyclist I now use them in both pairs of run shoes I own. They're great.
Remember to add your shoes to your Strava, it will let you know when to start looking for a new pair. I was surprised (even as a cyclist!) how soon it was time for more. Sure enough, when I got the notification.......the tread on the soles had some solid wear to it.
