I'm encountering some confusion with my secondary ISP, which seems to require us to manage our own router for routing public IP addresses. Is it typical for a large ISP to not handle this on their end? Should I consider switching ISPs to automate router management? I can assign my transit IP on our WAN, but this means I need to route other WANs behind that transit IP. Any insights?

It seems like you have your terms mixed up. Your secondary ISP is likely giving you routed subnet access, known as Provider-Aggregatable (PA) space. Just double-check their setup.
It sounds like you need to get more clarity on your current arrangement. I’d suggest directly reaching out to your ISP to confirm if they handle routing for you, versus if you need to set up BGP to announce your prefix. Once you know what they provide, you can configure your router/firewall appropriately.
There are different types of internet services out there! Typically, you have Dedicated Internet Access (DIA) where you might get a dynamic IP, and you can request a static one. In your case, since you're using your own public IPs, you're probably looking at IP transit, where you manage your own routing and can have multiple physical circuits for bandwidth.
Honestly, it sounds like you might not have the right service level. Most ISPs will usually provide a managed router for free when you sign up, which might take the weight off your shoulders.
