Just so you're aware, Bullse, Crossbows, regardless of category, all use your Dexterity. So even your strength-based fighter would benefit from having weapons with the thrown property (Daggers, hand axes, javelins, light hammers, spears and tridents) actually work properly as throwable attack weapons. A video game concession giving them 'returning' for free, or making the returning enchantment common on them would be perfectly acceptable in my opinion.
