Please help me find the document with instruction timings.

Not found in short, datasheet, programming manual, user manual.

Seek Cortex-M0 core documentation from ARM

Things like loads and stores will be impacted by assorted bus speeds, wait states and bus contention.

For practical purposes you should benchmark your code in a working system using the settings you plan on using. Utilize a scope, and evaluate transitions on GPIO pins. The M0 does not have a core cycle counter available in the ITM like M3/M4 cores do.

Found the Doc, thank you!

As I'm in the evaluation phase, benchmarking is rather impractical.
