About an advantage of write through

I think the issue was by ths following , Writes are traditionally done lazily -- the value may be modified again while it's still in the cache, so there's no point writing any one change out to memory just yet. However, a read may require a dirty cache entry which hasn't yet been written out to memory to be evicted to make room, in which case that entry will have to be written to memory before the eviction can take place.
For a write-through cache, the modified value is written immediately on write, so cache entries are never dirty. Because of this, they can be evicted without writing without risk of data loss.

what is the advantage of block file write

I hope this helps you . If I understand your question correctly, you are asking about the advantages of using larger blocks, rather than writing character-by-character.
You have to consider that each use of a system call (e.g. write()) has a minimum cost by itself, regardless of what is being done. In addition it may cause the calling process to be subjected to a context switch, which has a cost of its own and also allows other processes to use the CPU, causing even more significant delays.

hop of those help? Continue to use functions.php. If it starts to become a bit cluttered separate into includes. ie...
include_once('inc/cf7_custom.php');

Should I write code that takes advantage of Intellisense?

I wish did fix the issue. Intellisense still works just fine in F#, but at a module level rather than at a class level. I.e., I just typed in List. and once I typed the dot, VS Code (with the Ionide plugin providing F# Intellisense) gave me a list of possible completions: append, average, averageBy, choose, chunkBySize...
To get that benefit from your own functions, put them in a module:
module AddSub =
    let add2 x y = x + y
    let sub2 x y = x - y
    let add3 a x y = a + x + y
    let sub3 a x y = a - x - y
let a = 20
a |> AddSub.add3 5 10 |> AddSub.sub3 2 3  // Result: 30
let a = 20
a
|> AddSub.add3 5 10
|> AddSub.sub3 2 3
// Result: 30
