"Pregnant woman" is more precise than "pregnant person" or "pregnant female“. Pregnant woman specifies the gender as well as implying the sex (female or intersex, since males lack a uterus), while "pregnant person" only implies sex and "pregnant female" specifies the sex but not the gender.
"Pregnant person" is the least specific, "pregnant woman" is the most specific.
It's less accurate for the reasons you listed: it includes gender, which isn't always accurate and is unnecessary.
The problem is that there are trans men who exist, who may be pregnant. If asked if they are a woman or a woman who may be pregnant, they would answer no, which is incorrect in the larger context.
Pregnant people is naturally a superset of pregnant women, so pregnant women WOULD be more precise, if the advice applied only to pregnant women, which it almost never does. So that means we should almost never use pregnant women, as it's inaccurate.
Specificity should not be sought in the face of inaccuracy. For example, "brick house" is more specific than "house". So if I said "I live in a brick house", that should be better right? No, because it's wrong - I live in a wood house.
Per my original comment: "we want it [terms] to include every thing it should, and nothing it shouldn't." Pregnant woman doesn't include everything it should.
