Well, I understand that going back to default can be achieved by deletion of the control files. However, maintaining the control file provides the flexibility to change the port number as desired.
The system must not care whether there is a non-standard port specified in such configuration or port 22 by chance.
Thanks for your advice. It does provide a clean workaround for what I still perceive as a bug.

Title:
  ssh access on port 22 inhibited

Status in openssh package in Ubuntu:
  Incomplete

Bug description:
  Ubuntu 24.04.3 LTS

  ssh:
    Installed: (none)
    Candidate: 1:9.6p1-3ubuntu13.13
    Version table:
       1:9.6p1-3ubuntu13.13 500

  I had changed the ssh port thru /etc/systemd/system/ssh.socket.d/override.conf:

  [Socket]
  ListenStream =
  ListenStream = 24427

  The team requested to have that returned to the default port 22. So I
  changed the file to

  [Socket]
  ListenStream =
  ListenStream = 22

  With a recent update I could no longer ssh into the machine. Two solutions:
  1. Use sshd instead of ssh.socket
  2. Remove or rename the above control file so that it is not read.

  I.e. having port 22 defined in the controlfile breaks access.
  Annoying. A fix will be highly appreciated.

  Others ran into the same issue:
