Zooming User Interface (ZUI)
You probably know this, but in Google Maps at least, you can use browser zoom (ctrl/cmd +/-) to change the size of labels without zooming into the actual map.
------
Speaking of maps, I got to work a fun zoom project a few years ago: https://map.fieldmuseum.org/
We used https://openlayers.org/ and thought long and hard about how to best handle zooming and variable levels of information density & visual hierarchy. If you zoom all the way out, we just highlight where the building is relative to the surroundings. As you start to zoom in, we start to highlight major exhibitions and entrances. Then as you zoom in more, we start showing recommended paths, smaller exhibitions, etc. The label sizes try to scale up and down at each level, smoothly, in order to balance readability and density.
Eventually you can reach the max zoom level and the labels will just grow bigger and bigger, but the SVGs dynamically shrink so they remain pictograms and not just contextless-lines.
Then if you keep going, you eventually find microscopic easter eggs :)
The code is pretty jank (and abandoned), but it's FOSS vanilla JS/HTML/CSS, and the only dependency is on OpenLayers: https://github.com/arcataroger/openlayers_indoor_map

How to create my own custom indoor map and
I have found a few Javascript libraries that work with canvas elements that might do the trick, but that is to make a map that is not overlaid on an actual geographic map. If the latter is what you want, openlayers is probably the way to go. There is an abandoned project on GitHub that does an overlay: https://github.com/arcataroger/openlayers_indoor_map

Open-source indoor map built with OpenLayers + QGIS
After a few months of work, and with help from this community and many others, we've open-sourced an indoor venue map we built using OpenLayers and QGIS: openlayers_indoor_map

Zooming User Interface (ZUI)
I made a proof-of-concept text viewer with this in mind - https://github.com/aappleby/wideboard
