I have a large L-shaped executive desk, and I love it. It's massive, but it keeps stuff close at hand and adds some gravity and class to my home office. I don't know the brand, but I bought it at a furniture place that sells only business furniture. You'll love the artificial wood, it fights stains and cuts. However, I would recommend getting a glass cover for the top surface. I didn't and regret it. More on reddit.com

Have you considered building your own desk? Even with the price of wood being high, you can build a really spacious workstation for under 1k. This is what I use for my desk: https://www.homedepot.ca/product/home-decorators-collection-72-inch-x-25-5-inch-x-1-inch-acacia-kitchen-countertop-in-golden-teak/1001036553 for the desk top, and https://www.homedepot.ca/product/live-edge-28-inch-high-steel-furniture-legs-2-pack-/1001053164 for the legs. Even buy two of the counter tops and three of the legs. More on reddit.com

I get what you are going for - modern - but I like more simple stuff so some of the below may not be what you are after. Anyways.. Bush furniture makes a series of white L Shaped Desks. With cabinets and without. Some with hutches, some have sit stand options. They are typically for commercial applications, decent materials, easy to put together and are relatively bomb proof. https://www.amazon.com/s?k=bush+white+l+shaped+desk Personally I like the below. It's simple, (but weighs 185lbs!) and you can purchase whatever filing cabinets you want separately. You can add a hutch if you like. I've had something similar for almost 20 years and it's still rock solid. https://www.amazon.com/Bush-Business-Furniture-Studio-Shaped/dp/B08BGBV9VP/?th=1 This one with a sit stand option looked interesting as well. https://www.amazon.com/Bush-Furniture-Somerset-Position-Shaped/dp/B08DDHJKXD/?th=1 "Modern" options https://www.computerdesk.com/products/ultra-clean-design-l-shaped-desk-in-white-2 https://www.computerdesk.com/collections/l-shaped-desks/products/copy-of-modern-cappuccino-l-shaped-desk-with-file-drawer-open-shelving https://www.wayfair.com/furniture/pdp/mercury-row-senga-l-shape-executive-desk-w005160804.html Huh. Back to Bush with a modern slant. Variations of the same desk, different storage options and a hutch. https://www.officedepot.com/a/browse/white-corner-and-l-shaped-desks/N=5+553865&cbxRefine=578410/ https://www.officedepot.com/a/products/3260231/kathy-ireland-Home-by-Bush-Furniture/ https://www.officedepot.com/a/products/4619207/kathy-ireland-Home-by-Bush-Furniture/ More on reddit.com

3 decent sized monitors take up WAY more deskspace then people often think. Depending on your usage case a single ultra-wide monitor might offer the same workspace in a smaller footprint. My rule of thumb is if you have a dedicated office space there is really no such thing as a too big desk. More on reddit.com
