It's very good for the front-end and there's some good wisdom there it's hard to find elsewhere. But it doesn't really go into code generation in any depth, and the compiler he writes outputs C code. But it's a solid foundation and for what he does cover it's really good
In that reddit post someone links Wirth's books, they are good. Crenshaw's compiler stuff is alright too but kinda ends up cycle-shaving on the lexer which nobody cares about nowadays

Bitwise videos look okay to me at first glance - pretty much how I did it many years ago. Besides the Intel/AMD manuals you'll want an x64 opcode cheatsheet like https://wiki.osdev.org/X86-64_Instruction_Encoding or https://cs.brown.edu/courses/cs033/docs/guides/x64_cheatsheet.pdf
In the prototype stage you might prefer to use Python, Lua, JS, etc to output executable files.
If you're more interested in the frontend (parsing) and language design, you could make a simple bytecode interpreter and not worry about efficiency at all.

Have not read it myself, but I have heard good things about A Retargetable C Compiler Design and Implementation book explaining details on how lcc compiler is built.
I myself have learned about creating compilers from Let's Build a Compiler articles.
