Each map is of different sizes so the render distance varies in some maps. So if you want to have every team base in your viewing distance you should go for the biggest map of bedwars (for solos the biggest map I believe is Woodquarium) and set the render distance according to it. However I would like to add that setting the rendering distance high may affect your FPS negatively depending upon your system, if you have a decent system it shouldn't be an issue but if you have a low-end device I would suggest keeping it near 10 chunks because FPS has more priority than render distance.
