You will not get any visa when you enter the US. The visa, which you already have, is the thing that allows you to enter the US. At the point of entry, it becomes a temporary I-551 (permanent resident card, commonly known as a "green card").
The question you want to ask is whether you will become a conditional permanent resident as described in 8 cfr 216 and 8 USC 1186a. The answer should be no if you indeed enter after your second wedding anniversary, even though you have a CR-1 visa instead of an IR-1 visa. See, for example, Immigrant Visa for a Spouse of a U.S. Citizen (IR1 or CR1): What Is Conditional Residence? on the State Department website, which says (emphasis added):
If you have been married for less than two years when your foreign citizen spouse enters the United States on an immigrant visa, his or her permanent resident status is considered “conditional.”
That page links to Remove Conditions on Permanent Residence Based on Marriage on the site of US Citizenship and Immigration Services, which similarly says (emphasis added):
Your permanent residence status is conditional if it is based on a marriage that was less than 2 years old on the day you were given permanent residence. You are given conditional resident status on the day you are lawfully admitted to the United States on an immigrant visa or adjustment of your status to permanent residence.
The process is described in the (now obsolete) CBP inspectors' field manual. Despite its being obsolete, the relevant material (section 14.6) is still correct (emphasis added):
14.6 Conditional Residents.
Admission procedures for conditional immigrants (based on spouse or investment) are discussed in 8 CFR 235.11. Procedures are generally the same as for other immigrants, but in spouse cases, if the marriage upon which the visa is issued occurred more than 2 years prior to the date of admission, you must admit the alien unconditionally, regardless of the visa symbol on the immigrant visa. Conversely, if you encounter an immigrant visa classified as unconditional, where the qualifying marriage occurred less than 2 years before the date of admission, you must admit the immigrant conditionally.
