Last time I looked at Blazor it only had two options, which were both equally horrible for public websites.
You either had to ship a big and bloated WASM file, which was at least 10x the size of competing JS frameworks, and in some cases 100X the size. Or you had to render all dynamic parts of your website on the server, which made latency a huge problem, since your website feels sluggish between each interaction.
I don't know when it was the last time you took a look at Blazor, but Blazer server is extremely fast. I built some big corporate apps with it and never had any latency problems.
Were they internal or external apps? Because latency was the problem last time I looked, and it won't be super noticeable if you have the servers that close to you.
