systemd doesn't read logs from persistent storage by default

Not sure I follow the failing to start with two separate path entries, I'd expect it just to report it can't read one - same as if it did not have access for example. Unless it's to do with nesting or something strange.

Are you using two different tail inputs or specifying two paths in a single input?

I tried this:

[INPUT]
    Name              systemd
    Tag               systemd
    Systemd_Filter    _COMM=systemd
    Path              /run/log/journal
    Lowercase         On
    Strip_Underscores On
    DB                /fluent-bit/db/cursor1.db

[INPUT]
    Name              systemd
    Tag               systemd
    Systemd_Filter    _COMM=systemd
    Path              /var/log/journal
    Lowercase         On
    Strip_Underscores On
    DB                /fluent-bit/db/cursor2.db

and it failed with this error:
