I’d be cautious about dismissing a soft fork as simply nothing to worry about. Soft forks can have unintended consequences, even though your coins are still spendable.
As for a hard fork, when that occurs there is a chain split, and now anyone hold coins before the chain split have the same number of coins on both networks. Which network/chain you decide has the most value proposition is up to you to decide. That’s how Bitcoin Cash and BSV came into existence, for instance.
