Electrolytic capacitors do degrade over time. Putting aside Rifa and other paper capacitors, the only other type that is likely to fail are high voltage ceramic disc types. Other 250V interference X2 type will lose capacity over time. These are a common cause of low power all in one mains powered devices (radio door bells, mains digital time clocks, smart home plug-in mains sockets etc.)
Other capacitor types are normally fairly reliable (although for equipment that is over 40 years old, the less common failure modes may start to occasionally show up). And even if they have degraded, may not cause the symptoms you have.
What I’m saying is that after replacing the electrolytic capacitors that you suspected, I wouldn’t rush to start randomly changing the other capacitor types.
