Preferred Stock Screening Metrics

As the title states, I'm curious about what the community likes to use as their stock screening metrics, and how it compares to the metrics I use. Are there sectors that you strictly avoid, or solely look within, market cap or liquidity restrictions, etc…

For example, as an investor, I readily look for double-digit Revenue and EBITDA growth, EBITDA margin expansion, and a strong EBITDA to Free Cash Flow conversion (70%+).
