For a non-open data option, I work at UKHO, who publish over 15000 ENCs and coverage is fully global. I believe UKHO are one of the only hydrographic offices that maintain global coverage. As you say, most countries will chart their own territorial waters only.

Finally, I've found trace dataset suitable for the benchmarking, containing 100 traces from different parts of the world. It is described in the article called Dataset for testing and training of map-matching algorithms by Kubicka et al. (available on IEEE).
The dataset itself is stored on zenodo.org as an open-access dataset.

I constructed a 24 billion point lidar point cloud web service available with color information that might be suitable for this task. It is available in Entwine Point Tile format on AWS courtesy of Bohannan Huston and the City of Hobbs, NM. You can view it in Potree at https://hobbslidar.com.

Try Open Addresses database. It has over 500 million records. It is available for download here.
The good part is that it has data from all world regions.
I suggest you start with Latin America as it is one of the hardest nuts to crack when comes to address testing. Then do Europe, then Asia. Leave the USA for last as addresses are most standardized there ...

Apparently the z function available in the Geometry section of the field calculator works well with points. I was able to find a solution to a similar problem of that asked by the OP by using z(start_point($geometry)) in the field calculator.

As commented by @RussRoberts:
The current release of Collector does not support vector tile
packages. If you have vector data you can create just a tile package
and side load that into Collector or Publish it as a tile layer and
have it support Export Tiles(same for imagery). Here are the esri
provided basemaps
