Is the RTX 4060 enough for modern games?

Yes at 1920x1200. The 8GB RTX 4060 runs most current titles at high settings with good frame rates, and the 144Hz panel suits esports games. Demanding titles need settings lowered for very high frame rates.

Is 32GB of RAM worth it over 16GB?

For gaming alone 16GB is usually enough. 32GB helps with heavy multitasking, video editing, modded games and running a game alongside a browser and other apps.

Can I upgrade the storage or memory?

The 1TB SSD and 32GB of RAM are already generous. MSI's Cyborg line uses SO-DIMM memory and M.2 storage, so check the service manual for slot count and maximum capacity before buying upgrades.

How does it compare with a 15- or 16-inch gaming laptop?

It is smaller and easier to carry, but the smaller chassis has less cooling headroom, so fans run louder and sustained performance is lower than larger laptops with the same GPU. The 1200p screen is also smaller than typical 15- and 16-inch panels.
