I’ve been a backend web dev (now full stack) for over 10 years. Many things are rather boring CRUD apps. This is the part I enjoy least, but it can be dealt with rather quickly. The projects I enjoy the most are the ones where the business logic is rather complex, since that is almost always done on the backend. It’s a nice feeling, to build something custom for client that will fit their exact workflow and spit out the numbers or the reports or whatever that they need to make their business work efficiently. Where I work we decided against the cloud and use a docker based architecture on physical servers. There is also quite a bit of server administration / devops involved if your company does not have a specialised person. Many desktop apps have a server component, whether they are web apps or not. In these case there will be a backend component.
I self host a Bitwarden server fork called vaultwarden. It works with all the official Bitwarden apps and browser extensions and I am very happy with it. I never used 1password though so I cannot comment on any missing features.
