On-chain data access via institutional brokers for BTC

Anyone else finding it surprisingly difficult to get integrated, reliable on-chain data for $BTC through their primary institutional brokerage or liquidity provider? Most are great on spot and derivatives, but when you want deeper access to transaction volumes, UTXO age bands, or exchange flow metrics for proper analysis and strategy building, it often feels like you're left to piece together subscriptions from third-party data firms. The latency and data standardization across these disparate sources can be a real drag on systematic approaches. Are we still too early for this to be a standard offering, or am I just not asking the right questions from my current providers?
