For simple trails, I'd go with an XC type of bike. Full suspension if you can afford it although hardtail will work.One with a dropper post too again if it fits within your budget. As to make and model, there are just too many out there nowadays. Most modern mtb's have gone in the 1x direction. A lot of them are good too. Some of the Youtube channels I subscribe to do some bike reviews. Try searching on YT. That may help.
