You will definitely run into low volume issues if you try to bet on smaller, local leagues on an exchange. Premier League matches have millions passing through the order book, but niche games sometimes don't have enough players to match your exact stake at decent odds. I tried placing a bet on a lower-tier match last month and my order just sat there unmatched until kick-off.

If liquidity is dead, it's just better to stick to major leagues.
