This is not a useful strategy for good preference-ordering systems. "strategically" not making a second or third choice is on balance much more likely to cause you to fail to get your preferences, because the scenario you thought you were hedging against didn't happen.

It's easy to understand how approval voting works, as well. That's the primary advantage of approval over Condorcet: ease of understanding. "Vote for anyone you approve of and would be satisfied to see in office. This way, you can vote for candidates you like more, as well as candidates you think have a better chance of winning, and you don't have to choose whether to vote strategically to keep someone you don't like out of office or to vote for your favorite candidate. We tally all the votes, and the person with the most votes wins, which means they're the person approved by the most people."
While Condorcet is a bit more challenging to understand (the easiest explanation being based on "who would beat everyone else in a head-to-head race", leaving aside the cycle-breaking mechanisms), it's much more resilient against the need for strategic voting. In Condorcet, there isn't an incentive to vote strategically; just write down your preferences.
Approval does have scenarios in which strategic voting may be desirable, notably when a less mainstream candidate is close to overtaking the mainstream candidates and enough people are willing to drop their approval of the closest mainstream candidate. That's a dangerous strategy to try, because it also gives an opportunity for the most popular opposing candidate to try to win. The existence of that strategy is one of the biggest arguments for Condorcet over Approval.
So, the massive tradeoff here is:
Do you want a system that's trivial to explain to people with no additional complexity under the surface, trivial to adapt existing voting procedures and ballot designs for, and is better than FPTP along most axes, but still retains one of the notable flaws of FPTP, namely having particular scenarios that still encourage strategic voting? That's Approval.
Or do you want a system that's better than FPTP along pretty much every axis, encourages and benefits from honest voting with no "strategy" required or desired, but is a bit harder to explain to people and has some additional complexity under the surface, and is harder to adapt existing voting procedures and ballot designs for? That's Condorcet.
Also, frankly, if you're going to talk about systems that present voters with something easy to understand on the surface but have complexity under the surface that most people don't understand and that does cheat people, we already have that system in place: FPTP with the Electoral College, gerrymandering, myriad forms of voter suppression... Compared to that, both Approval and Condorcet are simple.
