Betta Fish: Need suggestions

So I just posted recently about if my tank is ready for a betta. I went to the lfs yesterday and they told me to bring the ph up since it’s low. They told me to add ph up 7.0 which u can see in the picture to the side. I also added more plants and a betta leaf as well as adding my heater. Gonna retest the water today to see how ph is. But idk what betta to get😂😂 and im very indecisive. What betta would u get for this 5 gal tank if it was yours??
