What weight are you??
All of those things will have an impact.
I did my first meet at 19 and 198lb. Only did something like 365/245/420, but I had a blast!!
Im 240lbs, 28yrs old, Male. Im not expecting to win anything I just would like to compete (more against myself than anything). All my numbers are Raw. No belt, straps, or wraps either. 300x3/230x3/406x3. I have just started strength training and will look into some PL competitions near me.
As far as strongman goes are there any novice competitions or do I need to be extremely strong for those?
There are indeed novice competitions, but not at every show. Check nastrongmaninc.com for upcoming comps and see if they have novice divisions. Also find a trainign crew around you so you can try the equipment.
At 240 you’re 9 lbs over the cutoff for LW. At your strength levels I wouldnt tell you to diet, maybe clean up your diet if its not the best, or do a water cut (just be prepared to be called a cheater on the intertubes if you do that) but you need to get stronger whether you go LW or HW.
Also start training your overhead - strict, push press or jerk - and your grip - double overhand deads, plate pinches, etc
