I used --force and now @angular-devkit/build-ng-packagr is gone from my package.json. Is this a problem?

That is expected as the package is deprecated and its APIs are now part of build-angular.

When doing ng update @angular/core @angular/cli, I'm getting

Package "@angular-devkit/build-angular" has an incompatible peer dependency to "karma" (requires "~5.1.0", would install "5.2.3")
Package "@angular-devkit/build-ng-packagr" has an incompatible peer dependency to "ng-packagr" (requires "^10.0.0", would install "11.0.2").
× Migration failed: Incompatible peer dependencies found.

If I do ng update @angular/core @angular/cli --force, then I get
