I suppose this would break code if someone tried to provide a non-str sep but that's not documented and unclear why someone would try that anyway

could it be a remnant of py2 compatibility? for public methods should we allow bytes in all places where a string is expected?

Not sure but on closer inspection doesn't seem to work in general case anyway:
>>> json_normalize({ 'foo' : { 'bar' : 0 } }, sep=b'.')
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/Users/williamayd/clones/pandas/pandas/io/json/_normalize.py", line 266, in json_normalize
data = nested_to_record(data, sep=sep, max_level=max_level)
File "/Users/williamayd/clones/pandas/pandas/io/json/_normalize.py", line 106, in nested_to_record
new_d.update(nested_to_record(v, newkey, sep, level + 1, max_level))
File "/Users/williamayd/clones/pandas/pandas/io/json/_normalize.py", line 91, in nested_to_record
newkey = prefix + sep + k
TypeError: can only concatenate str (not "bytes") to strSo just seems like a mistake

xref #27396 @simonjayhawkins some of these were just easy cleanups.
Didn't look through all but some of the others are more complicated and probably require in depth review
