An extension that might meet this need is [`jupyterlab-fonts`](https://github.com/deathbeds/jupyterlab-fonts/).

After `pip` or `conda` installing, it enables somes menu items, command palette items, and a sidebar for customizing font family, font size, line height, etc.

Alternately, you can customize it through the settings UI, but probably only via the old-fashioned JSON settings editor, as it hasn’t been updated to work with the form-based one.

However they are edited, the settings are stored in your jupyter application directory that persists between launches, and can be deployed in e.g. Binder with [`overrides.json`](https://jupyterlab.readthedocs.io/en/stable/user/directories.html#settings).
