They scale very well for web and db servers as well. You just put lots of containers/VMs on a single server.

AMD EPYC has a separate architecture specifically for such workloads. It's a bit weaker, runs at lower frequency and power and takes less silicon area. This way AMD can put more such cores on a single CPU (192 vs 128 for Zen 5c vs 5). So it's the other way round - web servers love high core count CPUs.

not really - you can certainly put lots of lightweight services on it, but they don't scale. because each core doesn't really get that much cache or memory bandwidth. it's not bad, just not better.

		Not true. You should look up Sienna chips and something like ASUS S14NA-U12. It has six DDR5-4800 channels, two physical PCIe 5.0 ports, two M.2 ports, and six MCIO x8 ports. All lanes are full-bandwidth. The 8434PN CPU gets you 48 physical cores in a 150W envelope. Zen 4c really is magic, and LOTS of bandwidth to play with.
