Very strong conservative values... well, yes and no. Conservative is not really a good term to use because those meanings change. But as for your question of liberal values, plenty. Here are a few examples:
1. Jacksonians often used anti-elite rhetoric against the "aristocracy." He often asserted that "yeoman farmers" and hillbillies" were the ideal representation of America. I don't know about you, but that sounds pretty similar to what many socialists nowadays say- just change "aristocracy" for "bourgeoisie" and "yeoman farmer/hillbilly" for "proletariat." Once he had popular support, he would instill his supporters.
2. Though there are some notable exceptions- most notable Grover Cleveland- many Democrats (W. J. Bryan in particular) ran on a sort of left-wing populist platform. Although there were many rich and upper class Democrats (the "Bourbon Democrats"), Many more Dems like Bryan often complained about "Eastern monied interests,"i.e., big businessmen and bankers.
3. Attractive to immigrants- the Democrat Party has always been attractive to new immigrants, such as Germans and Irish Catholics. Slightly later they would expand their scope of activities to Latin American immigrants. Pretty much the only immigrants they despised (and no, conservatives today don't despise immigrants, we just want to end illegal immigration) were Chinese- which carries over to today, where "affirmative-action" laws actually RAISE admission standards in college for Asians, in an effort to keep more of them out of college.
4. Direct democracy- this idea is that each new territory would hold a vote to decide whether slavery would be legal in that particular new state. This is comparable to the movement to abolish the Electoral College and establish a national popular vote.
5. This came later, but it's still before the supposed "Party Switch" happened in the sixties. I don't know if you've ever heard of Franklin Delano Roosevelt, but he instituted numerous government funded welfare programs, a pretty neoliberal idea. It was called the "New Deal" and its backers re-elected Roosevelt four times. It's also where the term "Green New Deal" comes from.
There are plenty more, but I'll stop here. Regardless, I don't think you've been paying attention to what I've said. The Republicans at that point were classical liberals, which are quite similar to the "conservatives" of today. They were not leftists, however desperately you try to paint them as such.
