I am curious

[ZeroYano]

I am leveling up my party to battle the red fur bear. I got my main party up until 8-9 and it consist of Landsknecht, Nightseeker, fortress, medic and runemaster and I was curious what would be the best choice of classes for a party? I was thinking of swaping out my runemaster with a sniper

Runemasters are more damage orientated and are the strongest damage dealer at this point in the game... and are amongst the strongest throughout the entire game. Fire/Ice/Volt Rune become pretty important later on, since it can protect you from elemental damage and also boost the damage of your party's elemental attacks by adding elemental weaknesses to an enemy.

At this point in the game, Snipers are more orientated to shutting down enemies attacks with the appropriate bind skill. Their arm bind skill is quite powerful against all the FOEs in the 1st land, since a lot of them rely on their arms to use most of their attacks. Later on, Snipers can be become potent damage dealers with Squall Volley, however your Sniper will need some way of improving their accuracy. Which means, using Spotter or inflicting the enemy with either Leg Bind, Blind or Paralysis.

Best party formation implies boring in EOs imo. For example, it may consist of a party of one Fortress and three Runemasters on the back. Just make one party that you like and feel comfortable to navigate the dungeon without great difficulty, especially since EO4 does allow flexibility in party formation, unlike EO1.

FYI, Sniper does considerably less damage (than Runemaster, at least) in the early game, but they are great in preventing incoming damage with their binding shots.
