Welcome Merry.
Helmets are really different. Find one that fits you and you can wear it all day. As far as wind noise goes, I keep a pair of these in a little case in the glovebox
https://www.etymotic.com/er20hd.html. I started wearing earplugs about 20 years ago when friends who worked in high noise environments started to notice hearing loss. The disposable foam ones work just as well but these are washable and I seem to loose one before they could wear out
I have a short pre ride ritual. Start scooter, turn bars both ways to be tire throttle isn't binding, squeeze both brakes separately to check brake light, check turn indicators and high beam, check tires for cuts.
Ear plugs in, helmet on, glasses on gloves on, roll scooter off of center stand apply front brake and and check for play in fork. Ride away.
Had a friend that was a commercial pilot who turned me on to the "pre flight check". It all takes less than a minute and you always know everything is working
Good luck finding the right scooter and ride safely
