I want to run the program:
g++ sfml.cpp -o prog -lsfml-graphics -lsfml-window -lsfml-system
gives an error:
warning: ignoring file '/usr/local/Cellar/sfml/2.6.2/lib/libsfml-window.2.6.2.dylib': found architecture 'x86_64', required architecture 'arm64'

The installation destination for current releases of homebrew on Apple Silicon Macs is /opt/homebrew/*.
This will also require a modification to your PATH statement to:
export PATH=".:${PATH}:/opt/homebrew/bin"
and optionally:
export PATH=".:${PATH}:/opt/homebrew/bin:/opt/homebrew/lib"
Homebrew installed Apple's command-line tools for Xcode which gives you an optimized C++ compiler (clang++) that probably would run circles around GNU g++.
You can see the list of available C++ libraries including those with g++ extensions:
clang++ foo.cpp --std=
For Apple Silicon, Homebrew changed where it stores things to /var. But you do need to upgrade Homebrew for that to happen.
If you still have older Homebrew /use/local binaries, perhaps via Migration Assistant, AND your PATH has this directory instead of, or maybe before the Apple Silicon Homebrew directory, that would explain your situation.
homebrew installs the Intel version of SFML, not the M1
