Should I take a 144h visa or a 72h visa or an L visa for China.

Hello,
I just got acquainted with the 144H00 visa and a few minutes ago I discovered the 72h00 visa.
I thought there was only the tourist visa L.
I'm going on a cruise from Tianjin port with my aunt. By taking my plane ticket, I did not see that the nearest airport is Tianjin.
So I took a plane ticket from Paris to Beijing, a 2-night hotel stay in Beijing and then a transfer from the hotel to Tianjin port.
Should I take a 144h visa or a 72h visa or an L visa for China.
