I don't know of one central resource that covers all of these topics. There are good articles on jemalloc and tcmalloc that discuss modern allocation strategies for general purpose allocators. There are articles from games development that discuss object pooling both in the context of C++ and in the context of optimizing GC languages like C# and Java as well as other specialized strategies like bump allocators, frame allocators, etc. Resources on learning modern C++ cover RAII and resources on learning Rust cover its approach. There are good talks on the fairly new polymorphic allocator model for C++ that cover the motivations for it and use cases. Experience with modern C++ is valuable for understanding how much you can do with mostly stack allocation and how you can write non library code without ever writing a raw new or delete.
