Grass fed beef is likely better in more regards than one. Since they eat "greens", they thus have a higher intake of vitamin K1, which then gets converted into K2. This vitamin is part of a system of calcium deposition, with K2 activating the enzymes that put the calcium in appropriate places. Prior to the knowledge, medical pros added to their kill count by prescribing calcium and vitamin D supplements without K2 increase for older people, this wound up with the calcium being deposited in their arteries.
The evidence seems to indicate that conjugated form may be beneficial to animals, and not quite clear on humans. Nothing seems to indicate harm and perhaps a slight decrease in obesity. This chemical, due to shape, differs from normal linoleic acid. This is idenfitied by the nomenclature adding conjugated to the term.
Obesity and its comorbidities, including type 2 diabetes and cardiovascular disease, are straining our healthcare system, necessitating the development of novel strategies for weight loss. Lifestyle modifications, such as exercise and caloric restriction, ...

With red meat, the matter of heme intake does matter a bit. The solution seems to be a simple pragmatic one. Eat some berries or other polyphenol-based product along with vitamin C to stop it from reacting in a damaging manner to colon cells. As if by instinct, humans often do adulterate beef with tomato products to enhance pleasure of beef during consumption. And absolutely do not cook and consume red meat with most other polyunsaturated fats aside from what is already inside of it(so don't eat veggie oil fried beef, which is essentially all restaurant beef).
Adulteration with calcium containing or cholrophyll containing foods would also be prudent for the same reasons. Cheese, green vegetables.
Red meat and processed meat intake is associated with a risk of colorectal cancer, a major cause of death in affluent countries. Epidemiological and experimental evidence supports the hypothesis that heme iron present in meat promotes colorectal cancer. This meta-analysis of prospective cohort...

The omega-6:3 ratio is much better in grass-fed beef as well. Thus, even if CLA is harmful, the ratio is superior to that of grain fed beef and certainly better than consuming a raw supplement.
CLAs derived from supplement apparently are a different occurring acid than the ones that occur in natural animals. Never mind that pressing and the refine the oil does involve the use of compounds like hexane.
CLA is found in certain foods and available as a fat-burning supplement. This article explains if CLA can help you lose weight.

Throw in some sardines to broaden the net of micros and have an easy source of DHA/EPA. Alpha-linolenic acid can be converted to DHA and EPA but the process is inefficient. The beef is one source but fatty fish like sardines are a bounty, although with other vitamins and minerals.
Be sure the meat is clearly grass-fed and not just organic.
Keep on eating the grass-fed beef if your budget can accommodate it, but venturing out can be beneficial as well. Elk eating could arguably be more healthy since "elk farms" are essentially forests and the goes to having the landowner keep it as a forest.
