If you want to ban all abortion in the entire USA and not leave it to the States, for the reasons you did a good job of explaining, the the only really correct way to do that is via a Constitutional Amendment.
Reversing Roe v. Wade isn't going to do it. That just sends it back to the States. Abortion was legal in some states prior to Roe V. Wade, so you are really working to create a new Federal Law. That is what amendments are for.
This was attempted in the 1970s and early 1980s several times in the Senate. The last time, in 1983 a full vote was held in the Senate, it failed to reach a majority, 49-50. Of course for it to advance to the states it needs 2/3 vote, so it wasn't even close.
Realistically do you think that such an Amendment could pass either house today? I do not.
I agree this is the easiest, though I contend that personhood is the key and therefore no amendment is required.

Not quite. Read what Blackmun wrote about personhood.

Truthfully no. I don't think there are more than a handful of Congressmen and Senators who are actually pro-life.
Most of the "pro-life movement" today is about codifying and regulating abortion. They want to use it to raise money, they don't have any actual interest in ending it. Their position is nearly identical to the position that many early 19th century Whigs held on slavery.
Abortion was being performed at the federal level in the 1960s and before Roe.
It makes a difference who the president is and who makes federal abortion policy.
