The CFPB ruling will (is?) certainly to be appealed.
Besides the SEC, you also have the FTC, FCC, CFTC, CPSC, PCAOB etc run by groups of Directors who can't be fired at will.
The FHFA and OCC are led by single Directors.

Grounds for Removal
Although not always specified in statute, it appears that the heads of financial regulators, in
contrast with Cabinet Secretaries, typically do not serve at the pleasure of the President (“at
will”). Instead, most regulators may be removed only if a higher “for cause” threshold is met. The
one clear statutory exception is the OCC’s Comptroller of the Currency, who “shall hold his
office for a term of five years unless sooner removed by the President, upon reasons to be
communicated by him to the Senate.”
“For cause” removal limits the ability of a President to remove, or threaten to remove, an
appointee solely for political reasons. According to one law review article, “The distinguishing
feature of [independent] agencies is that their principal officers are protected against presidential
removal at will.” According to another,
A requirement that members serve a fixed term of years is an essential element of
independence, but alone is not sufficient. The critical element of independence is the
protection—conferred explicitly by statute or reasonably implied—against removal except
“for cause.”
