I buy a few suits every year and I wear one almost every day.
The sites listed as searched are cheap thus their office attire looks and is cheap. Just like men's suits if you want good quality you have to pay the price for quality. These shops might have decent selections in person but more expensive suits aren't usually big sellers so you tend to find them in a physical retail spaces easier than online.
Unfortunately, a decent suit is going to carry a price tag of at least $300 (unless on sale) - my closet is full of quality suits purchased in-person after trying on and oftentimes tailored post-purchase. I often self-tailor as I am usually able but with more complicated adjustments I take them to the tailor.
There's no substitute for quality textiles, quality fabric, and quality construction.
Most of the supposed workwear for women these days looks like casualwear - like they're going out to hang out with friends or go to the beach or more directly have zero clue what professional wear looks like. I live in a tropical climate and you wouldn't believe the things that women wear to the office thinking they look business casual - their attire is the equivalent of a man in a see-through tank undershirt with basketball shorts i.e. not professional attire regardless of how you try to dress it up. When I tell a member of my staff to wear a suit I mean wear a suit not some stretchy straight legged almost see through "trousers" that are actually yoga pants and I don't mean some see-through spaghetti strap crop with breasts falling out. It isn't about policing their personal style it is about how they present as they represent the company. If your staff looks low-rent the assumption is going to be that the product/service is low rent - which makes negotiations more cumbersome than necessary. And isn't about telling women what to wear it's about expecting women and men to dress appropriately for their role at work.
Placemats - I'm in the US but don't you have like Nordstrom's, Macy's, Dillard's, Saks, or similar there? I really think you need to go in person to try the suits on - to touch the fabrics to ensure you are purchasing quality.
