My first question is whether you're on one of the new plans or one of the old plans. This is actually important because the old plans are provisioned differently. The old plans use Visible's cloud APN while the new plans run off Verizon's. A lot of people have complained that Visible's was pretty terrible. The old plans were $25/mo if you had Party Pay. The new plans start at $30, but don't require any hoops.
After that, I'd note that if you're not on the Visible+ plan, you are going to be on a lower QCI (Quality of Service Class Identifier) than most of the traffic on the network. So if others are using the network, you might experience slowness, lags, and hangs. Verizon's network isn't in the best capacity position in a lot of areas so this can be meaningful.
Verizon's low-band 5G is also not great since it uses dynamic spectrum sharing rather than having dedicated 5G spectrum.
If you're on one of the old Visible plans, I'd pay the extra $5 and get on one of the new plans. You'll need a new SIM card for it, but it's probably worth it to get off the cloud core that has generated a lot of complaints. If you're on the new $30 plan, it might be worth trying the $45 plan for a month and seeing if you get better results with the 50GB of premium data. After that, you should probably try T-Mobile or AT&T.
EDIT: as an aside, it's probably not that "higher frequencies used for 5G don't go as far or penetrate as effectively" simply because, unless you're on Visible+, you don't have access to any of those higher frequencies. Legacy Visible plans and the current $30 Visible plan only have access to low-band 5G using the same frequencies as LTE.

You can try AT&T for free using their 14-day free trial on Cricket (https://www.cricketwireless.com/free-trial.html, note that it's only 3GB of data) and you can test out T-Mobile for a whole 3 months if you have an eSIM device (https://www.t-mobile.com/offers/free-trial). If you can, it's definitely worth trying an alternative carrier since they're now offering free trials (Verizon also offers one for 30 days: https://www.verizon.com/support/verizon-test-drive-faqs/).
