It honestly sounds like this is a conversation for your doctor, considering the possible heart thing. Regardless of public policy (which will be to protect the most people and reduce hospital burden), individual health concerns will always be the final answer to your question. One reason for the healthy to get vaccinated is to reduce the risk for someone who can’t be vaccinated for some complication or another.
It’s also worth noting that both flu and COVID are dangerous and severe enough to not want to get them. (Way more so than the common cold, which doesn’t take long to get over.) Hence the yearly flu booster that some folks opt for.
Honestly, the political side of this will optimize towards reducing the burden COVID takes on the health system. If there are too many people with severe cases in the hospital, the rest of us can’t get treated for other ailments. That sort of thing just doesn’t happen with the flu regularly, and it’s the sort of thing public policy is supposed to solve.
