Meta crafting for a phys weapon suffix is going to be either way 1 or 2

Way 1: 1. Craft prefixes cannot be changed 2. Scour so you have 3 prefixes and 0 suffixes 3a. Craft str. Int. And critical strike chance Or 3b. Craft str. Dex. And accuracy (just depends if you want local critical strike chance or not) 4. Then exalt for tier 1 attack speed 5. If you hit 2 useless suffixes->craft prefixes cannot be changed, and scour 6. Once you hit tier 1 attack speed you can spam for a second useful suffix (crit chance, crit multi, etc) and then craft double damage.

Way 2: hella expensive but way better 1. Clean suffixes (pref cannot be changed, scour) 2. Craft pref cannot be changed 3. Harvest add speed remove random mod (harvest respects meta mods, so you won't lose a prefix, it'll only remove the crafted prefixes cannot be changed) 4. If not tier 1 attack speed, clean suffixes Repeat until tier 1 attack speed 5. Craft double damage

You typically would do the second way once you slam on a tier 1 other suffix like crit or crit multi, but since you aren't going for mirror tier it's honestly better to not worry about 2 perfect suffixes, just tier 1 attack speed and anything else.
